--- Comment #1 from nzkarix@gmail.com 2009-11-16 00:58:37 --- Further testing shows that the installer is getting stuck while it tries to install PhysX. I tried to install PhysX manually from winetricks and it gets stuck too.
Both the installer and the winetricks PhysX install get stuck while trying to call msib5d0.tmp. On a 'CallDllFunction' and it just sits there sleeping.
